DSD vs DSF vs DFF Files Audio. What is difference [Article]

Share 

Audio Basis - educational articles

Read below about difference between DSD, DSF, DFF files audio.

DSD vs DSF vs DFF

DSD (Direct Stream Digital) is one bit audio format for high resolution music. The format based on sigma delta modulation. Read details about DSD >

Music in DSD format may be stored into DSF and DFF files (.dsf and .dff file extensions respectively). Both DFF and DSF are DSD files.

I.e. DSD files is common term, that include both DFF and DSF audio files.

 
WARNING:
Input DSF, DFF, ISO (1-bit audio) is supported in Audiophil-E, PROduce-R and configurable Modula-R
Output DSF is supported in maximal PROduce-RD and configurable Modula-R
For ISO tracks, DSF, DFF with length more 3 minutes FREE demo mute 2 second silence in the output middle

However besides these kind of files, SACD ISO (.iso extension, 1-bit audio ISO) is DSD file too. SACD ISO contains text metadata, that may be extracted during SACD ISO to DSD conversion.

 

 

DSD vs PCM

 

Sometimes one bit DSD considered as more qualitative alternative for multi bit PCM. However it is not simple matter, that defined by implementation. Read more about DSD versus PCM >

 

 

DSD converters

 

All DSD files (DSF, DFF, ISO) may be converted each to other without loses, when conversion don't alter sample rate.

DSD resampling and other processing (even elementary gain changing) lose quality, comparable with PCM resampling. However it is not big matter for pro-audio processing.

DSD audio players

 

DSD playback may be implemented two ways:

  • Convert to PCM and playback at PCM DAC (digital analog converter),
  • Playback straight at DSD DAC.

In general, second option is preferable. But real result depend on hardware and software implementation.

DSF vs DFF for players

 

Playback sound quality is the same for both DFF and DSF.

DSF and DFF at DSD player audio files

 

DFF file don't support music metadata (song name, album, performer, artwork) standard way. However, the metadata may be stored as ID3 format into DFF file's chunk (internal data block). For access to the metadata, DFF file player must be able to recognize ID3-chunks.

DSF specification support the metadata. However may be issues with artwork size and/or resolution for DSF audio player.

To playback multichannel music at DSD player, the music is downmixed into stereo on fly. Sound quality of downmixing is implementation matter. To save hard disk space, you can pre-downmix it.

DSF versus DFF compression method

 

Current DSF specification note raw uncompressed packing only [1].

DFF may be stored as uncompressed as compressed by DST (Direct Stream Transfer) method [2].

 

 

DSF versus DFF editing

From sound quality point of view, for editing DSD files, file format is not matter.
